The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 99.
The divisibility rule for 99 is a method by which we can find out if a number is divisible by 99 or not without using the division method. Check whether 297 is divisible by 99 with the divisibility rule.
Step 1: Check if the given number is divisible by both 9 and 11. First, check divisibility by 9: Add all the digits of the number. For 297, 2+9+7=18, which is divisible by 9.
Step 2: Next, check divisibility by 11: Alternately subtract and add the digits of the number. For 297, calculate 2-9+7=0, which is divisible by 11.
Step 3: Since 297 is divisible by both 9 and 11, it is divisible by 99.
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 99.
